  • 6.5x47L vs 6.5cm question

    So with lapua making SR primer cases for CM now. Is there any advantage to running 47L vs cm?

    Use is PRS events only

    I'm eager to see answers to this also from folks that have run both. I'm leaning toward the Creedmoor in my next build due to more powder capacity and adequate room to load long bullets and still fit in an AICS magazine. I would also consider both flavors in a 6mm but cannot live with the short barrel life. I think the lesser recoil of the 6mm version is the best way to go if cost is no object. One of my rifles is a .243 in an XLR Element chassis. It will get re-barreled in one of these when it is done...won't be long.

      Advantages are really in the eye of the shooter. While I don't own a 6.5CM we do have a 260, a 6.5 SAUM on the way, and I run the 6.5x47L in my match rifle. Working on having a 17/18" 6.5x47 built as well.

      Ill tell you why I still prefer it as my 6.5 short action cartridge of choice; it's ridiculously efficient, simple to load for, and the brass last for ever. What little velocity and powder capacity the x47 gives up to the 6.5CM it makes up for in case design. It sounds insane but that little cartridge can withstand some serious pressure. Im not necessarily recommending you push it that hard just letting you know it can be pushed to make up some of its velocity loss.

      All in all despite my affinity to the 6.5x47 it's really just preference. One isn't necessarily better than the other.

        The 6.5 Creed ia pretty much just a 6.5x47 Improved no? Its a wash.

          I just went through this process, was going to build a 6.5x47L but because of the SR primer Lapua brass, going Creed was a no-brainer. Pretty decent factory ammo if you're feeling lazy, plenty of brass options if you want to reload it too. I just finished stage 1 of load development, found a node right at 2900 with a 139gr Scenar. I'm going to play with depth a little bit to hone it in, but that was my goal, to pump that 140-class projectile at 2900. Mind you, this is a 28" heavy palma barrel, but I think it's going to be a good match rifle.

            I think something worth mentioning is the x47L is known to shoot the heavier projos well with Varget. Varget is much more available than H4350 which the Creedmoor was practically designed to use. If you're buying Lapua brass anyways, the x47L is generally a few bucks cheaper per 100 and more available to boot.

              Honestly those 2 points where very good sells.for me. It responds well to varget and I dont have to fight for h4350, and brass seems to be easier and cheaper in lapua

                If you handload and are certain that you will never need factory ammo, I'd go with the 47L. If you hunt, and especially if you travel and hunt, or ever think you might need to run out for some ammo in a pinch...for sure go with the Creedmoor. If I had to choose purely on accuracy I'd go with the 47L but the gain is imperceptible now that there's Lapua SRP brass for the Creedmoor.

                  I have been told that the 260 has a greater capacity than either the CM or the x47. Can anyone confirm or disprove this? Apologies for going a bit off topic.

                    Yes it does, but not enough to worry about. Hand loading pretty much equals them out.

                      I had the same conundrum 3 yrs ago, but with the mentioned 2 and the 260. I love to shoot Lapua brass so it was a 47L vs 260 question for me. I chose the 260 basically in a coin flip. Since Lapua started making CM brass, I am pretty sure if I had to make this choice now I would go with the CM. It is really taking off, rifles and ammo everywhere for it. I like my 260's and probly have enough Lapua brass put up to last me a lifetime so I will keep what I have.

                            This, I have both and prefer the 47L. I don't think you can go wrong with either.

                              Have all 3. I prefer x47L. The most accurate round I have ever loaded for and load development is super easy, brass life is insane. It is insanely accurate with Varget with low single digit SD's.

                                Had a reamer ground to my specs. All I ever shoot is 123's. Hvy rifle has shot several 10 shot sub 1/2" groups. Light hunting rifle with #5 Brux has never shot 1/2" 5 shot group, but has done 5/8". No since in looking at rifle when I miss. I will stick with my 260's

                                  I don't think 6.5 Creed Lapua brass has been out long enough to make a determination between it and x47. It'd be cool to know though. Lapua/creed, 50 fps gain in velocity, yes or no? As accurate? Theoretically it should last equally but....

                                  One thing for sure, it's been hard looking elsewhere with 10 years, almost 35 firings on my 6x47l brass, and most cases still going strong!

                                    I shoot 6.5x47 Lapua. 140 grain bullets at 2,800 FPS with only 37.4 grains of Varget. Brass lasts forever, feeds from a mag like the chamber is sucking them in, and accuracy is there. I cleaned a PRS club match stage yesterday with 10/10 at 525 yards on head targets and the spotter said I center punched every shot. The cartridge is amazing.

                                          I didn't start annealing till around 7 years ago but since then I anneal every one or two firings with a Bench Source.

                                          I own my own reamer and custom dies which afford minimal resizing which in turn helps the cases last longer. Flash holes reamed, necks turned, weight sorted,

                                          In the beginning as l experimented with loads I realized I was using loads that were too hot. Based this mostly on velocity when I finally bought a chrono, otherwise it was hard to judge pressure just looking at the case and the bolt wasn't even stiff yet. I think those few really hot loads were the cases that eventually the primer pockets got loose on, maybe 20 or so over the years. The rest have been warmish loads and I'm amazed the cases still hold a primer and most hold them well. Right now it's 3125 fps with a 28" and 105's because the barrel is slowing a tad, was 3150 fps last year. I used to get over 3200 with R17 and the original barrel. On my sixth barrel now.

                                            I was just overhearing a smith talking about this same topic with a shooter. Was saying for some reason on average the 6.5x47 vs the 6.5creed always had a tendency to be more accurate. Something to do with the chamber size of the x47 possibly attributing to this.....anyone else ?

                                              It does seem that every posted grouping is one ragged ass hole. Yes I know shooter and other factors play in but it does seem to stooopid accurate every time I see it posted

                                                  Iīm in love with my 6.5 Creedmoor. I use a 26" Bartlein and load nosler brass with 43gr of RL-17 and this is how it shoots. SD goes a little high on very hot days, but normally stays around 10
